Point cloud


Option menu providing 4 alternate methods of point distribution in a voronoi point cloud.

Each distribution type may have it's own attribute(s) that are unique. The only common attribute found among each distribution is Seed.


Places particles by choosing uniformly-distributed random numbers along each coordinate axis.

Num points

type int
default 100
The number of points (particles) to generate around the object. Each point will give rise to a voronoi cell. There may be fewer fragments than cells, depending on how they intersect the object.


type int
default 0
The random number sequence seed value. Change this to get a different arrangement of points.


Places particles such that the approximate distance between them is the same. Gives rise to more evenly shaped cells.

Approx num

type int
default 100
The number of points to aim for. This will not be achieved exactly, since the aim of this distribution mode is equally spaced points.


The radial option creates a radial distribution of voronoi cells from a center point. This option uses the the same Num point and seed attributes as the uniform option. The dispersion of cells around the center point is determined by the Radial bias attribute.

Radial bias

type float
default 1.0
minimum 0.5
How much influence the center point has when distorting particle positions.

The generated cells, as seen above, is merely a preview of the fragments that will be generated upon a collision. The actual center point is determined by the point of the collision.


Tries to create clusters of points, to give more variation in cell size.

Num clusters

type int
default 10
minimum 2
The number of clusters to place amongst the original particle set. Particles are moved towards the nearest cluster.

Cluster bias

type float
default 1.0
How much influence the cluster has on the final particle position.


Regenerate during sim

type bool
default True
Enable this to re-generate the point cloud when different objects are broken during a simulation

Radial center at impact

type bool
default True


type string
The particle shape in which the generated points are stored

Data name

type string
default cell
The name of the custom data to be attached to fragments, identifying (integer) the particle whose voronoi cell they originate from
